Filter by:The purpose of this research study to determine if treating recurrent malignant gliomas with another person's (donor) immune system cells known as aCTL cells, will be safe. This study will also try to determine if persons who receive aCTL's are more or less likely to survive their brain tumor than persons who had similar tumors in the past. Approximately 15 patients will be enrolled at UCLA.
RATIONALE: Biological therapies, such as cellular adoptive immunotherapy, may stimulate the immune system in different ways and stop tumor cells from growing. Donor T cells that are treated in the laboratory may be effective treatment for malignant glioma. Aldesleukin may stimulate the white blood cells to kill tumor cells. Combining different types of biological therapies may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best way to give therapeutic donor lymphocytes together with aldesleukin in treating patients with stage III or stage IV malignant glioma.
The high-grade malignant brain tumors, glioblastoma multiforme (GBM) and anaplastic astrocytoma (AA), comprise the majority of all primary brain tumors in adults. This group of tumors also exhibits the most aggressive behavior, resulting in median overall survival durations of only 9-12 months for GBM, and 3-4 years for AA. Initial therapy consists of either surgical resection, external beam radiation or both. All patients experience a recurrence after first-line therapy, so improvements in both first-line and salvage therapy are critical to enhancing quality-of-life and prolonging survival. It is unknown if currently used intravenous (IV) therapies even cross the blood brain barrier (BBB). Superselective Intraarterial Cerebral Infusion (SIACI) is a technique that can effectively increase the concentration of drug delivered to the brain while sparing the body of systemic side effects. One currently used drug called, Bevacizumab (Avastin) has been shown to be active in human brain tumors but its actual CNS penetration is unknown. This phase I clinical research trial will test the hypothesis that Bevacizumab can be safely used by direct intracranial superselective intraarterial infusion up to a dose of 10mg/kg to ultimately enhance survival of patients with relapsed/refractory GBM/AA. By achieving the aims of this study we will determine the toxicity profile and maximum tolerated dose (MTD of SIACI Bevacizumab. We expect that this project will provide important information regarding the utility of SIACI Bevacizumab therapy for malignant glioma, and may alter the way these drugs are delivered to our patients in the near future.
This is a phase I study to evaluate the safety and tolerability of Sorafenib in combination with Temodar and radiation therapy in patients with newly diagnosed high grade glioma (glioblastoma, gliosarcoma, anaplastic astrocytoma and anaplastic oligodendroglioma or oligoastrocytoma). The mechanism of action of sorafenib, an oral multikinase inhibitor, makes it an interesting drug to investigate in the treatment of patients with high grade glioma as this agent has anti-angiogenic activity and inhibits other pathways such as Ras, Platelet-derived growth factor (PDGF) and fms-like tyrosine kinase receptor-3 (Flt-3), which are potential targets against gliomas.
Currently, there are few effective treatments for the following aggressive brain tumors: glioblastoma multiforme, anaplastic astrocytoma, gliomatosis cerebri, gliosarcoma, or brainstem glioma. Surgery and radiation can generally slow down these aggressive brain tumors, but in the majority of patients, these tumors will start growing again in 6-12 months. Adding chemotherapy drugs to surgery and radiation does not clearly improve the cure rate of children with malignant gliomas. The investigators are conducting this study to see if the combination of valproic acid and bevacizumab (also known as AvastinTM) with surgery and radiation will shrink these brain tumors more effectively and improve the chance of cure.
This phase I study evaluated a Gene Mediated Cytotoxic Immunotherapy approach for malignant gliomas, including glioblastoma multiforme and anaplastic astrocytoma. The purpose of this study was to assess the safety and feasibility of delivering an experimental approach called GliAtak which uses AdV-tk, an adenoviral vector containing the Herpes Simplex thymidine kinase gene, plus an oral anti-herpetic prodrug, valacyclovir, in combination with standard of care radiation.
This is a Phase I study of Nanoliposomal CPT-11 in patients with Recurrent high-grade gliomas. Patients must have a histologically proven intracranial malignant glioma, which includes glioblastoma multiforme (GBM), gliosarcoma (GS), anaplastic astrocytoma (AA), anaplastic oligodendroglioma (AO), anaplastic mixed oligoastrocytoma (AMO), or malignant astrocytoma NOS (not otherwise specified). Patients who are wild type or heterozygous for the UGT1A1*28 gene will received Nanoliposomal CPT-11. The total anticipated accrual will be approximately 36 patients (depending upon the actual MTD). The investigators hypothesis is that this new formulation of CPT-11 will increase survival over that seen in historical controls who have recurrent gliomas because CPT-11 will be encapsulated in a liposome nanoparticle, which has been seen to reduce toxicities from the drug.
Background: The optimal treatment of anaplastic gliomas is controversial. Standard of care in most centers is still radiotherapy. This phase III study compared the efficacy and safety of radiotherapy vs chemotherapy in patients (pts) with newly-diagnosed, supratentorial gliomas of WHO grade III. Methods: Pts were randomized 2:1:1 between June 1999 and February 2005 in 34 German centers to receive (i) a 6-week course of radiotherapy (1,8-2 Gy fractions, total dose 54-60 Gy) or (ii) four 6-week cycles of CCNU at 110 mg mg/m2 on day 1, vincristine at 2 mg on days 8 and 29 and procarbazine at 60 mg/m2 on days 8-21 or eight 4-week cycles of 200 mg/m2 temozolomide on days 1-5. Treatment was stopped prematurely at disease progression or occurrence of unacceptable toxicity. At this time or at disease progression, treatment in the radiotherapy group was continued with one of the chemotherapies (1:1 randomization) and with radiotherapy in both chemotherapy groups. The primary endpoint was time-to-treatment-failure (TTF) defined as progression after radiotherapy and one chemotherapy in either sequence, or any time before if further therapy could not be employed. Assuming a 50% improvement in TTF of starting with chemotherapy, 318 pts were to be enrolled to provide 80% power to achieve statistical significance at a one-sided level of 0.05.
Background: In order to survive, brain tumors must have a network of blood vessels to supply it with oxygen and nutrients. The tumors produce substances that enable new blood vessels to form. Tandutinib and Bevacizumab are experimental drugs that may prevent new blood vessel formation and thereby slow or stop tumor growth in the brain. Objectives: To determine the safety and side effects of Tandutinib in combination with Bevacizumab in patients with brain tumors. To evaluate the response of brain tumors to treatment with Tandutinib and Bevacizumab. Eligibility: Patients 18 years of age and older with a malignant brain tumor for whom standard treatments (surgery, radiation and chemotherapy) are no longer effective. Design: Patients receive treatment in 4-week cycles as follows: Tandutinib by mouth twice a day every day and intravenous (through a vein) infusions of Bevacizumab over 90 minutes (or less if well tolerated) every 2 weeks. Treatment may continue for up to 1 year, and possibly longer, as long as there are no signs of tumor growth or serious treatment side effects. Patients are evaluated with magnetic resonance imaging (MRI), computed tomography (CT) and positron emission tomography (PET) scans before starting treatment and then periodically to determine the response to treatment. Patients have physical and neurological examinations every 4 weeks and blood tests every 2 weeks. They complete quality of life questionnaires every 4 weeks.
